The braking distance, D, of a car is directly proportional to the square of its speed, v. When d=5, v=10Find d when v=70
Answers
$\implies d=kv^2$
substitute the given values, $5=k(10)^2\implies k=\frac1{20}$
now, $d=\frac{1}{20}\times( 70)^2=\frac{70\times70}{20}=245$

Explanation:
The equation is 6x+8y=48. An x-intercept is the point where the data crosses the x-axis. All points on this line will have a y-coordinate of 0, so we replace y with 0 and solve:
6x+8(0)=48
6x=48.
Divide both sides by 6:
6x/6=48/6
x=8.
We go to 8 on the x-axis and plot the point.
A y-intercept is the point where the data crosses the y-axis. All points on this line will have an x-coordinate of 9, so we replace x with 0 and solve: 6(0)+8y=48
0+8y=48
8y=48.
Divide both sides by 8:
8y/8 = 48/8
y=6.
We go up to 6 on the y-axis and plot the point. We then draw a line through these two points.

Refer the figure.
Step-by-step explanation:
Let x be the number of times Emma mows the lawn
and y be the number of hours Emma babysits
Emma earns $6 each time she mows the lawn and $8 per hour for babysitting i.e.
She is saving up to buy a new pair of jeans that cost $48.
i.e.
The y-intercept of the line is the point when x=0,
y-intercept is at (0,6)
The x-intercept of the line is the point when y=0,
x-intercept is at (8,0).
The shaded area is determined by putting x and y zero.
False so the region is away from origin.
The solution is the shade area above the solid line.

Not telling you the answer that just the steps, that would be cheating.
Step-by-step explanation:
1. Mulitply 1000 by the fraction.
2. Simplify it(the numbers 1000 and 2 to 500 and 1)
3. Then divide the exponents(you know this I taught you:)
4. You then will get your answer! (hint: it has a negative exponent :)
5. Please try not to use Brainly next time, try it yourself:) or I may take points off, ask me next time.
When x ≠ 0, the expression x²/2x⁵ × 1000 simplifies to 500/x³. This is obtained by simplifying the fraction and then multiplying by 1000.
To simplify the expression (x²/2x⁵) × 1000, we can start by simplifying the fraction within the parentheses.
First, let's deal with the fraction x²/2x⁵. We can simplify it by using the rule of exponents, which states that x^m/x^n = x^(m-n) when dividing with the same base. In this case, we have x²/2x⁵, so:
x²/2x⁵ = (x²)/(2x⁵) = (x²/x⁵) * (1/2) = x^(2-5) * (1/2) = x^(-3) * (1/2).
Now, we have the fraction x^(-3) * (1/2). To simplify this further, we can rewrite x^(-3) as 1/x^3. Therefore, the expression becomes:
(1/x^3) * (1/2) = 1/(2x³).
Now that we've simplified the fraction within the parentheses, we can multiply it by 1000:
(1/(2x³)) * 1000 = 1000/(2x³) = 500/x³.
So, the expression x²/2x⁵ × 1000 simplifies to 500/x³ when x ≠ 0.
